A -;-.sand1paper 245 shown Figs; 2' and 3is pref *1 45 detailed; objectis the use ofthe holder erably madeofa proper size by cutting standi invention a hand sand paper hclder for securinr a fabrictherecnlerifelt a i ard sheets in four parts, these sheets therefore being the size of the plate and have diagonally opposite corners which fold over the straight marginal edge 19 of the plate. If desired, several layers of sand paper may be placed on the bottom of the plate.

' The clamping device or clip 26 is formed of a strip of metal, this having a general S- shape in cross section, with a large bend 27 adapted to fit in the inside of the curl of the plate as indicated at 28. There is a reverse bend 29 in the strip forming the clip of rather sharp curvature, this being adapted to fit over the straight portion 19 of the marginal edge of the plate. This strip has an upper terminating end 30 adapted to extend on the outside of the curled portion of the margins of the plate and grip the sand paper,

holding it firmly in place. These clips or clamps are preferably made of resilient metal and are sufficient to hold several layers of sand paper or only one layer as desired by the operator.

In the construction of Fig. 4 I show a bufiing cloth 31 which may be of woven fabric or of felted material. This preferably has the corner portions which fit behind or inside of the curl of the plate somewhat chamfered as indicated at 32 to allow the clips to fit snugly in the inside of the curl of the plate. This bufiing material takes the place of the sand paper and may be used with any suitable composition to give a butting or polishing to the work in hand.

In Fig. 1 I illustrated the approved method of grasping the holder, in which it will be seen that the palm of the hand and the fingers are substantially flat against the upper portion of the web part 12 of the plate. The little finger fits under the marginal curl at one edge of the plate and the thumb fits into the marginal edge of the other curl. These curls are positioned substantially in correct relation to the thumb and the little finger by cutting the plate oblong instead of square, as indicated by the different dimensions of the sides 13, 14 and 15, 16.

Various changes may be made in the principles of my invention without departing from the spirit thereof, as set forth in the description, drawings and claims.

I claim:

1. A sand paper holder having a flat metal plate with the opposite marginal edges having an upward and an inward curl, sand paper fitted over the bottom of the plate and over the curled marginal edges, said paper being turned under the opposite edges of the curl .of' the plate, and clamps fitting in the curled portion of the plate and over the marginal edges of the paper.

2. A sand-paper holder as'claimed in claim 1, the clamps being somewhat S-s'ha-ped, curved to conform to the curl of the plate and the folded edge of the paper.

3. A sand paper holder having a metal plate with diagonally opposite corners having an upward and inward curl, sand paper fitted on the bottom surface, and means to secure the paper at the diagonally curled corners, the inside of the curl of the corners being adapted for engagement by the thumb and little finger of one hand of the operator.

4. A sand paper holder as claimed in claim 3, with means for securing the paper comprising detachable clamps adapted to engage the plate at the curled corners, and the sand paperat the fold over such corners.

5. A sand paper holder having a flat plate formed rectangular with diagonally opposite edges with the corners cut in a straight line, said corners being curled upwardly and inwardly and the sheet of sand paper fitted on the under surface of the plate on the outside of the curled portions and folded over the straight portions'of the corners the inside of the curl of the corners being adapted for engagement by the thumb and little finger of one hand of the operator.

6. A sand paper holder as claimed in claim 5, with clamps to secure the paper formed of S-shaped strips of metal having a curved portion to fit inside the curl of the plate and having another curved portion to fit over the straight portion of the corners of the plate and over the outside of the upper portion of the sand paper.

7. A sandpaper holder having an oblong rectangular plate of metal having two diagonaily opposite corners cut on a straight line, the plate adjacent said corners being curled upwardly and inwardly, and metal clamps adapted to hold a sheet of sand paper on the bottom surface and on the outside of the curled portions of the plate the inside of the curl of the corners being adapted for engagement by the thumb and little finger of one hand of the operator.

8. A sand paper holder as claimed in claim 7, the sheet of sand paper being adapted to be cut in the form of an oblong rectangle with diagonally opposite sharp corners, and an S-shaped metal clamp fitting inside the curl of the metal and on the outside of the sand paper adjacent the sharp opposite corners.

9. A sand paper holder having a flat metal plate with diagonally opposite corners upwardly and inwardly curled, a sheet of sand paper fitted over the bottom surface of the plate and the outside of the curled portions, the curled portions being positioned to allow fitting of the little finger and the thumb of one hand underneath on the inside of the curled portions and the palm on the flat upper surface of the plate.

10. A sand paper holder having a flat substantially oblong rectangular plate of metal with the opposite diagonalcorners cut off on astraight' line and the plate adjacent I "such corners curled upwardly and inwardly,

and a pair of. S-shaped metal clamps adapted to secure sheets of sand paper having opposite diagonal corners folded over the straight portions of the corners of the plate at the curl, the curled portions of the plate being positioned whereby the little finger and the thumb of the operators hand may be fitted inside and partly underneath the plate at the said curled portion.

In testimony whereof I have signed my name to this spec'ifieation.

RALPH W.-MARIS.
